WATCHMANS CLOCK Application filed. August 29, 1927. Serial No. 216,210..

This invention relates to improvements in watchmens clocks.

The primary object of the inventionresides in a watchmans clock of the kind to be 6 mounted upon the inside of a door and by which the visits of a watchman may be recorded and in which is embodied an automatic means for recording the time of the actuation of the door lock-by an authorized person having a key or by an unauthorized person making a forced entrance by jimmyingthe look. I

Another object of. the invention is to pro vide a watchmans clock having a recording 1 chart for recording the time of the visit of a watchman thereto, and. on which chart, the

time of closing and opening of the door to which it maybe attached is also recorded. 1 p A further object of the invention is the pro- 0 vision of a time lock recorder in which a time chart is punched by the actuation of the lock bolt to an extended and retracted position.

With these and other objects in view, the

, invention resides in certain novel construction and combination and. arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are.

illustrated in'the accompanying drawing,.in 3 which: a Figure 1 is a rear elevation of a door with my invention applied thereto. I 2 Figure 2 is a front elevation of the same.

' In carrying my invention into practice, I

make use of a suitable casing 10 which includes a body portion 11 for the reception'of any suitable well-known form of time pieces or. mechanism wherein is included an hour hand or arbor 12 actuated in the customary hour of time.-

manner by a gear train 13. The body of the casing is providedwith a swinging cover 14L held in a closed'position by a key controlled lock '15 for preventing opening of the cover by an unauthorized person.

' Within the body portion 11 of the' casing 10 is a frame 16 which acts as a support for the works of the time piece employed in con- 7 nectionwiththis invention. The frame'also' includes a plate 17 which constitutes a writin table whose oflice I will describe hereinafter. i

- The hourhand arbor has a disk 18 secured th reto and as shown, said disk carries a plu rality of dialretaining spurs 19 adapted to penetrate a paper dial 2O and hold the same in position to rotatewith the arbor whereby each of a type-capable of being punctured, 7

mutilated or'otherwise suitably marked by a recordv or actuating instrument or' scribe.- The dial is divided radially as ates bylines 25 which extend frointhe inner concentric circle to theouter edge ofthe dial, each radial line being indicative of one-half an hour whileevery other line isidentifiedby a numeral indicative of an;l1our,-whereby the space between each numeral. represents one The casing 10 is to be secured to'a'swing ing door 26 by means of attaching lugs 27 and securing elementsin the nature of screws 28. In this manner, the casing may be arranged upon the inside of the door'as illustrated in Figure 1 of the drawings. Co-

- acting with the. permanent markings of the dial- 20 and fixed within the casing .10 is a pointer 29. Under this pointer are sliding spurs or punch rods 30 and 31, the former being slidable through the frameglfi and through an opening32 in the door 26. The 7 free end of this spur is exposed from the outside of the door and is adapted to beactuated by'a night watchman or' authorized person 'ried by the watchman.

with a collar or shoulder 35 which normally holds a pointer 36 of the spur in a retracted position. Likewise the spring holds the outer :2 end of the spur in position where it may be reached bya suitable controlling key, not shown. .The spur 30 and its adjuncts censtitute'a mechanism for marking the inner concentric portion of the dial. 7

The mechanism formarking the outer concentric portion of the dial consists of the aforesaid spur 3lwhose point 37 is adapted to move through an aperture 38 in the plate 17. The outer end of the spurextends into a housing 39 within whicha lock bolts is slidably mounted and which lockbolt is movable to a position beyond the outer side of the casing for reception in a keeper 41 mounted on the door jamb The lock bolt tO has its top side edge cut-away to provide a cam 42, there being concave recesses d3 on opposite sides of the high spot of the cam. The outer end of the spur 31 is normally held within one of the recesses 43 by a spring 44 which bears against a collar &5 mounted on the spur. The body of the lock bolt is slotted as at 45, the top wall of which is provided with a rack bar 4 .6 for co-acting engagement with a pinion t? fixed to the end of a stub shaft 48 which extends rearward from the barrel d9 of a key actuated lock mechanism 50. The lock 50 is mounted in the door 26, while the stub shaft 48 extends through the frame 16 and has its bearing in the housing 39.

In the operation of the lock recording mechanism, it will be seen that when a key is inserted in the lock 50 and given a turn, the barrel of the lock will turn and cause the pinion a7 to extend the lock bolt into the keeper 41, by reason of its co-action with the rack bar 4L6; During this movement of the lock boltto an extended position, the high spot of the cam 42 will force the spur 81 toward the dial 520 and which spur leaves an impression or puncture upon the dial by reason of the pointed end 37 and which marking will of said forced entrance will be duly recorded 7 on the dial or chart.

The paper disk 20 is applied to the arbor shaft 12 to present the face of the same outward, whereby the punch rods 30 and 31 penetrate the disk from the rear side, thus causing a raised or embossed work on the face of the same. This assures an easy and accurate reading of the punch marks.

What is claimed as new is 1. A look recorder comprising in combination with a casing having a revolvable dial therein, key actuated lock mechanism including a slidable lock bolt, a cam on said bolt, there being recesses in the latter to form said cam, a punch rod having one of its terminals disposed in one of said recesses, the other end of said rod disposed adjacent said dial, and spring means urging said first terminal into said recess, whereby on sliding said bolt said cam is effective to urge said rod against the action of said spring for punching said dial, substantially as and for the purpose described.

2.- A lock r corder comprising in combina-' tion with a casing having clockwork mechanism therein, a perforable dial on one side of said casing and revolvable by said mechanism; key actuated lock mechanism having a barrel on the other side of the casing, a turnable shaft partly disposed in said casing, a lock bolt slidably mounted within the casing and movable by said shaft; a cam on said bolt, the latter having a recess therein on each side of said cam, a punchrod having one of its terminals in said recess, the other terminal of said rod disposed adjacent said dial, and spring means urgingsaid first terminal into said recess, whereby on actuation of said lock mechanism to turn said shaft said cam is effective, on sliding movement of said bolt, to urge said second terminal, against the action of said spring, into contact with said dial for punching the latter to show the time of actuating the lock mechanism.

In testimony whereof I have ailixed my signature. 7

appear in the outer concentric field 22. The

same operation occurs whenthe lock bolt is moved to a retracted position, thus a record will be left upon the dial during each actuation of the lock 50 to record the time of exit and entrance through the door. Should an unauthorized person attempt to force an entrance by jimmying the lock bolt, the time
